本文實例講述了CKeditor富文本編輯器使用技巧之添加自定義插件的方法。分享給大家供大家參考，具體如下：
首先就是在CKeditor的plugins目錄下新建一個目錄qchoice：
qchoice目錄下的結構如下：
然后， images中如下：
dialogs中如下：
我們先來看plugins.js文件的內容：
(function() {
CKEDITOR.plugins.add("qchoice", {
requires: ["dialog"],
init: function(a) {
a.addCommand("qchoice", new CKEDITOR.dialogCommand("qchoice"));
a.ui.addButton("qchoice", {
label: "qchoice",//調用dialog時顯示的名稱
command: "qchoice",
icon: this.path + "images/qchoice.jpg"http://在toolbar中的圖標
});
CKEDITOR.dialog.add("qchoice", this.path + "dialogs/qchoice.js")
}
})
})();
再來看qchoice.js文件的內容：
CKEDITOR.dialog.add('qchoice', function (editor) { //要和plugin.js 中的command 一致
var escape = function (value) {
return value;
};
return {
title: '', //對話框標題
minWidth: 500, //對話框寬度
minHeight: 600,//對話框高度

之后就是config.js配置文件的內容了：

CKEDITOR.editorConfig = function( config ) {
config.toolbarGroups = [

{ name: 'extent', items: ["qchoice"] }
];
config.toolbar_Full = [

];
config.image_previewText=' ';
config.filebrowserImageUploadUrl = 'uploadFiles';
// config.extraPlugins = 'justify';
config.extraPlugins += (config.extraPlugins ? ',justify' : 'justify');
config.extraPlugins += (config.extraPlugins ? ',qchoice' : 'qchoice');
// config.extraPlugins="linkbutton";
//

//
// config.extraPlugins="ijuzi";
// config.extraPlugins="iti";
config.removeButtons = 'Underline,Subscript,Superscript';
// Set the most common block elements.
config.format_tags = 'p;h2;h3;h4;pre';
// Simplify the dialog windows.
config.removeDialogTabs = 'image:advanced;link:advanced';
config.image_previewText=' ';
config.entities = false;
};
好啦，到這里，自定義插件就算是放入成功了。咱們自定義的插件主要的邏輯結構就是在qchoice.js文件中，可以改變它的內容，來實現不同的功能。
好啦，本次記錄就到這里了。
